Low oil and adding oil.

5:30 AM and leaving for work which is 30 miles away and later a 90 mile trip for business, "ADD OIL" indicator comes on. 4,200 miles and I have 42 % oil life remaining. No time to go to dealer for an oil change. Most repair shops that sell oil open at 7/8 am and I need to be 120 miles away by 2 pm.

Re: Low oil and adding oil.

I would 1st verify that it is actually low by checking the dipstick if you haven't already done so. If it is low, I would think that you are Ok adding Mobil 1 of the correct viscosity and grade, or closest that you have.

Re: Low oil and adding oil.

The expected oil consumption on the CTS-V is about a quart every 1000 miles so - according to my dealership. I use one about that, sometimes less when not getting into the boost/rpm that much. Your consumption will vary base on driving habits. I believe the owners manual states you should add oil within 500 miles of the indicator coming on. I usually keep a quart of mobile 1 in the trunk, and just add it as soon as the message comes on. The message means you are at least 1 quart low.

Re: Low oil and adding oil.

Got the same warning this weekend at almost exactly the same number of miles (4000-something) ... embarrassing to say, but I'll need to look into what viscosity/grade is appropriate for my '12 V - don't know it off the top of my head.

I don't believe that for one minute...that sounded like something the dealers would say back in the 80's. No offense, just don't buy in to that statement. Engineering is way better than that and the materials used are top notch on todays vehicles. I have over 30k on mine and no oil comsumption whatsoever.

I agree with this statement. Your dealer should not be telling you to expect oil consumption of 1 qt every 1000 miles. That is not normal! You have something else going on and I certainly would not wait until the indicator comes on to add oil. I would be checking weekly to keep it topped off if I had your kind of consumption.
